VALVE.

Application led June 22, 1925. Serial No. 38,637.

The present invention relates to a valve, and has particular reference to a valve adaptedto withstand the wear of an abrasive passing therethrough.

An important object of the invention is to provide a valve comprising a housing having a. plurality of ports therein, said valve having. a compressible tubular member eX- tending through the housing,l which is adapted to be compressed to control the effective opening thereof.

Another object of the invention is to provide a valve having a compressible member therein which/ can readily be removed and replaced when it has become worn.

Other objects and advantages ofthe invention will become 'apparent during the course of the followingdescription.

Thev drawing is a longitudinal section' .20 through the valves in operation.

" This invention is particularly well-adapted for use in an abrasive system wherein an abrasive held in suspension in water is continuously circulated through a piping system controlled by valves. An ordinary valve is not suitable in this system as the abrasive action is detrimental 4to the valve parts so that the life of the valve isvery short necessitating frequent repairs and 're- 3o placements.

The numeral 5 designates one pipe of a system adapted to contain a iiow of abrasive 6. The valve'v is designated in its entirety by the numeral 7, and comprises a housingl 8 having a .plurality of ports. The valve is provided with a seat 9 and a plunger 10. he plunger 10 is carried bythe valve stem 11 rotatableby means of the wheel 12. The

stem

l through the cap 13 carried by the va ve and held 1nposition -b means of the union 14.l

the valve between the I Extendin throug seat 9 an the plunger 10 is a rubber hose 15..

'The hose 15 may b e constructed of any suitv415 able fabric and is to rubber, althou li rubber hose has been -found to be entire y satisfactory. vThe hose is clamped in the ports by means of the u -a lateral opening therein,

bushings lf-a'nd 17. The 'bushin 17 is pro- I0 vided with the threads 18 .wheri'y con:

on my beA hdwith the pipe 15- 11 is screw-threadedly o rable' not necessarily restrictedand and sp! right-hand valve of the drawings shows in heavy lines the hose as at 19 inopen position, and in dotted lines as at 20 in a compressed position whei'eby the iow of abrasive is completely shut oif. Any intermediate adjustments can easily be made. The

hose is fiexible so that it can be compressed jas indicated in the drawings when the valve stein 11 has been operated by means of the wheel 12 without injury.

Ifit is desired a pair or Amore of valves may be arranged in series so that one valve canl be adjusted to give'y the desired iow through the pipes, while the other valve can be used merely to entirely close or entirely open the hose connection to the pipe 5.

When the hose has become worn it can be removed from within the housing and a new length can be placed in position. l

It is'to be understood that'the form'of the invention herewith'shown and described .is to be taken as the preferred embodiment vof the same, and that various .changes in the shape, size and arrangement of parts may be- 1. A valve of the character comen v prising a housing, 'a compressible member running through said housing, means for compressin said member, and bushings arranged wi n the housing at opposite ends thereof for securing said member inv ace,
